27.03.2014 Von kleinen Plastikmännchen über Nudeln zu Prototypen für die Industrie – inzwischen kann man mit 3D-Druckern fast alles drucken. Herausfordernd wird es erst, wenn die „Drucke“ sehr akkurat und klein und dann noch aus schwer bearbeitbaren oder teuren Materialien gefertigt sein sollen. . Die Wissenschaftler am Laser Zentrum Hannover e.V. (LZH) setzen sich genau mit dieser Thematik auseinander. Auf der Hannover Messe 2014 zeigen sie, wie sie den Laser nutzen, um winzige Implantate mit Gedächtnisfunktion oder komplexe Formen, wie die Hörschnecke des menschlichen Innenohrs, zu fertigen.

Il va faire beau ce week-end, les barbecues vont chauffer. Des experts recommandent de privilégier les viandes marinées... à la bière. Un groupe de scientifiques européens a constaté que la viande marinée à la bière réduisait les hydrocarbures aromatiques polycycliques (HAP), une susbtance qui se forme lors de la cuisson des viandes sur un barbecue. Certains de ces HAP ont des propriétés cancérigènes. L’étude, réalisée par des chercheurs de l’université de Porto, a été publiée dans le «Journal of Agricultural and Food Chemistry». . Les experts ont testé la cuisson au barbecue sur plusieurs steaks de porc: sans marinade, marinés à la bière blonde, à la pils sans alcool et à la bière noire. Pour la viande qui n’avait pas subi de marinade, les proportions de HAP excédaient les moyennes admises.

L'Institut de recherche en immunologie et en cancérologie (IRIC) de l'Université de Montréal (UdeM) en collaboration avec la Banque de cellules leucémiques du Québec de l'Hôpital Maisonneuve-Rosemont a récemment réalisé une percée majeure grâce à la culture de cellules souches leucémiques en laboratoire, ce qui permettra d'accélérer le développement de nouveaux médicaments anticancéreux. Dans une récente étude publiée dans Nature Methods, les scientifiques décrivent comment ils ont réussi à identifier deux nouveaux composés chimiques qui permettent le maintien des cellules souches leucémiques lorsque celles-ci sont cultivées à l'extérieur du corps. Cette importante avancée ouvre la voie à l'identification de nouveaux médicaments anticancéreux pour contrer la leucémie myéloïde aiguë, une des formes les plus agressives de cancer du sang.

Researchers have discovered a blood test that they say can predict with greater than 90 percent accuracy if a healthy person will develop mild cognitive impairment or Alzheimer’s disease within three years.
Gust MEES's insight:
He added the researchers consider the study’s results a “major step” toward a biomarker test that “could be useful for large-scale screening to identify at-risk individuals.”

The integration of consumer electronics with advanced imaging and analytical platforms holds great promises for medical point-of-care diagnostics and environmental rapid field testing for pollutants and viruses. A recent example is a Google Glass application and a server platform for instant, wireless diagnostic testing of a variety of health conditions and diseases. This technology allows Google Glass wearers to use the hands-free camera on the device to send images of diagnostic tests that screen for conditions such as HIV or prostate cancer.

At the dawn of rapid prototyping, a common predication was that 3D printing would transform manufacturing, spurring a consumer revolution that would put a printer in every home. That hasn't quite happened---and like so many emerging technologies, rapid prototyping has found its foothold in a surprisingly different field: Medicine.

Surgeons have used metal screws to reassemble broken bones for years, but there are drawbacks: if the metal corrodes, they've gotta come out. Biodegradable screws aren't as strong, and can cause inflammation. So a team of Harvard and Tufts scientists came up with screws and plates that are as tough as metal, but biodegradable. The trick? They're made out of silk.
